RESUMO
Stability of the total phenolic content, ascorbic acid, total carotenoids and antioxidant activity in eight fruit beverages was analyzed. The influence of storage temperature (4, 8 and 11 °C) during the product shelf-life (20 days) was evaluated. Pomegranate Juice presented the highest values for antioxidant activity by DPPH⢠assay (552.93 ± 6.00 GAE µg mL(-1)), total carotenoids (3.18 ± 0.11 ßCE µg mL(-1)), and total phenolic content (3967.07 ± 2.47 GAE µg mL(-1)); while Splash Blend recorded the highest levels of ascorbic acid (607.39 ± 2.13 AAE µg mL(-1)). The antioxidant capacity was stable at 4 and 8 °C for the first 8 days of storage; while carotenoids and ascorbic acid were slightly degraded through the storage time, possibly due to oxidation and/or reactions with other compounds. The results suggest that the observed variation during testing could be related to storage conditions of the final product.
